Abstract

A device for stripping and receiving cladding material from an elongated body includes a flexible bag means having an upper portion adapted to surround a first section of an elongated body and a lower portion extending below the first section of the elongated body for receiving and retaining cladding material removed therefrom and first and second laterally extendable sleeve members which are attached to opposing sides of the upper portion of the bag means and adapted to surround adjacent sections of the first section of the elongated body. The bag means and sleeve members define a sealed enclosure about the elongated body sections. Each sleeve member has an expandable length greater than adjacent sections of the elongated body which they surround whereby the extendable sleeve members permit the bag means to be moved into positions below each of the adjacent sections of the elongated body surrounded by each sleeve member to receive and retain cladding material stripped therefrom.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A device for stripping and receiving cladding material from an elongated body comprising: a flexible bag means having an upper portion adapted to surround a first section of an elongated body and a lower portion extending below the first section of the elongated body to receive stripped cladding material;   a first retractable and extendable sleeve member surrounding a second section of the elongated body extending from one side of said first section and having a predetermined retractable length and extendable length;   said first sleeve member having the inner end attached to the upper portion of said bag means and the outer end adapted to be releasably sealed to the second section of said body member at a distance from the inner end equal to 1/2 the length of the first and second sections of the elongated body;   a second retractable and extendable sleeve member surrounding a third section of the elongated body extending from the other side of said first section;   said second sleeve member having the inner end attached to the opposing side of the upper portion of said bag means and the outer end adapted to be releasably sealed to the third section of said body member at a distance from the inner end equal to 1/2 the length of the first and third sections of the elongated body;   said bag means and said sleeve members defining a sealed enclosure; and   means providing protected access to the interior of said bag means from the exterior of said bag means;   said sleeve members permitting said bag means to be moved into selected positions below each of the sections of said elongated body to receive and retain cladding material stripped therefrom.   
     
     
       2. A device in accordance with claim 1 wherein said bag means and sleeve members are formed of a flexible transparent plastic material. 
     
     
       3. A device in accordance with claim 1 further including means providing protected access to the interior of said bag means from the exterior of said bag means whereby an operator's hands can be inserted within said sealed enclosure to perform stripping operations. 
     
     
       4. A device in accordance with claim 1 wherein the protected access means include a pair of adjacent arm and glove means sealed to one side of the flexible bag means. 
     
     
       5. A device in accordance with claim 1 further including a tool pouch means attached to the inner surface of the flexible bag means intermediate the arm and glove means. 
     
     
       6. A device in accordance with claim 1 further comprising means for introducing negative air pressure into said bag means during removal of said cladding material. 
     
     
       7. A device in accordance with claim 1 further comprising means for introducing a liquid spray into said bag means during removal of said cladding material. 
     
     
       8. A device for stripping and receiving cladding material from an elongated body comprising: a flexible bag means having an upper portion adapted to surround a first section of an elongated body and a lower portion extending below the first section of the elongated body for receiving and retaining cladding material removed therefrom;   first and second laterally extendable sleeve members releasably and sealingly attached to opposing sides of the upper portion of said bag means and adapted to surround adjacent sections of said first section of the elongated body;   said bag means and sleeve members defining a sealed enclosure;   said sleeve members each having an extendable length greater than said adjacent sections of the elongated body;   whereby said extendable sleeve members permit said bag means to be moved into positions below each of said adjacent sections of said elongated body to receive and retain cladding material stripped therefrom.   
     
     
       9. A device in accordance with claim 8 wherein the length of said first section of the elongated body enclosed by the upper portion of said bag means is substantially equal to the length of said bag means and the lengths of said adjacent sections of said elongated body are less than the lengths of said sleeve members when fully extended. 
     
     
       10. A device in accordance with claim 9 wherein the lengths of said adjacent sections of said elongated body are one-half the length of said sleeve members when fully extended. 
     
     
       11. A device in accordance with claim 8 wherein said bag means and sleeve members are formed of a flexible transparent plastic material. 
     
     
       12. A device in accordance with claim 11 wherein said transparent plastic material is polyethylene. 
     
     
       13. A device in accordance with claim 8 further including means providing protected access to the interior of said bag means from the exterior of said bag means whereby an operator's hands can be inserted within said sealed enclosure to perform stripping operations. 
     
     
       14. A device in accordance with claim 13 wherein said protected access means include a pair of adjacent arm and glove means sealed to one said of side bag means. 
     
     
       15. A device in accordance with claim 14 further including a tool pouch means attached to the inner surface of said bag means intermediate said arm and glove means. 
     
     
       16. A device in accordance with claim 8 further comprising means for introducing negative air pressure into said bag means during removal of said cladding material. 
     
     
       17. A device in accordnace with claim 8 further comprising means for introducing a liquid spray into said bag means during removal of said cladding material.
